Comparative Behavior of Plutonia-238Base Fuel Forms with and Without Curia-242Additions.

摘要

Mechanical behavior of plutonium-238oxide and cermet radioisotope fuel forms during reentry from space operation is expected to be dependent upon the age of the fuel. A program to determine aging effects by accelerating helium generation is described. The results,the problems encountered,and the conclusions relevant to heat source technology determined during this fuel aging program are discussed.
